Types of Pregnancy Discrimination

Reviewed by Prue Alderton (PA), Editor-in-Chief — Pregnancy Discrimination Practice. Updated May 2026.

Pregnancy discrimination claims arise under several legal theories, each with different requirements and different strengths depending on the facts. Many cases involve more than one theory simultaneously — for example, a failure-to-accommodate claim under the PWFA combined with a termination claim under the PDA when the employer fires rather than accommodates. Understanding the distinctions helps you and your attorney evaluate which theories apply and which provide the strongest basis for recovery.

Disparate Treatment (PDA / Title VII)

Disparate treatment is the foundational theory for pregnancy discrimination claims: the employer intentionally treated the employee less favorably because of her pregnancy, childbirth, or related medical condition. Most pregnancy discrimination cases are analyzed using the McDonnell Douglas burden-shifting framework from McDonnell Douglas Corp. v. Green, 411 U.S. 792 (1973). Under this framework:

• The plaintiff establishes a prima facie case: she belongs to the protected class (pregnancy); she was qualified for and performing her job satisfactorily; she suffered an adverse employment action; and the circumstances suggest discrimination (e.g., a non-pregnant comparator was treated more favorably, or the adverse action closely followed pregnancy disclosure).
• The employer then articulates a legitimate, non-discriminatory reason for the action (performance, restructuring, position elimination).
• The plaintiff must show that the employer's stated reason is pretextual — false, inconsistent, or insufficient to explain the adverse action.

Pretext is the battleground in most pregnancy discrimination cases. Evidence of pretext includes: timing (adverse action shortly after pregnancy announcement, return from leave, or near the due date); disparate treatment (similarly situated non-pregnant employees with the same alleged performance deficiencies were retained or treated better); inconsistent explanations (the employer's stated reason changes, or the documentation of performance problems only begins after pregnancy disclosure); and direct evidence (supervisor comments about pregnancy, maternity leave, or anticipated childcare obligations).

Failure to Provide Equal Treatment (PDA — Young v. UPS)

The PDA contains an "equal treatment" clause requiring employers to treat employees affected by pregnancy the same as other employees who are similar in their ability or inability to work. This became the basis for the Supreme Court's ruling in Young v. United Parcel Service, 575 U.S. 206 (2015), which held that an employer cannot provide light-duty accommodations to employees injured on the job or covered by ADA disabilities while refusing to accommodate pregnant employees with similar temporary restrictions. The Young analysis requires courts to ask: does the employer's accommodation policy impose a significant burden on pregnant workers? If light duty is available for non-pregnant employees with comparable restrictions and the employer denies it to a pregnant employee, a triable issue of discrimination exists. Young claims have been particularly important in physical labor, healthcare, and service industry employment where light-duty accommodation is common for workplace injuries.

Failure to Accommodate (PWFA)

The Pregnant Workers Fairness Act (PWFA), enacted in December 2022 and effective June 27, 2023, created an affirmative accommodation obligation that goes beyond the PDA's equal treatment requirement. Under the PWFA, covered employers must provide reasonable accommodations for "known limitations" related to pregnancy, childbirth, or related medical conditions unless the accommodation would cause undue hardship. "Known limitation" is broadly defined and includes physical or mental conditions that are limitations even if they would not qualify as disabilities under the ADA. Routine pregnancy discomforts — nausea, fatigue, mobility limitations, lifting restrictions — can qualify.

The PWFA's list of potential reasonable accommodations includes: more frequent or longer rest breaks; sitting when the position normally requires standing (or the reverse); drinking water, eating, or using a restroom more frequently; receiving closer parking; adjusting work schedules; receiving light duty; working remotely; taking leave; and temporary suspension of one or more essential job functions. The last category — temporary removal of essential functions — goes further than ADA accommodation law, which generally requires essential functions to be retained.

Failure to engage in the interactive process is itself a violation. An employer that simply denies an accommodation request without discussing alternatives, proposing modifications, or exploring whether undue hardship actually exists has failed its PWFA obligation. Terminating an employee rather than accommodating her known pregnancy-related limitation is a per se PWFA violation and gives rise to full Title VII remedies.

Failure to Promote

Denying a deserved promotion because the candidate is pregnant, because she is expected to take maternity leave, or because the decision-maker assumed she would be less committed or productive as a parent is pregnancy discrimination under Title VII. These claims often involve "stray remarks" evidence — statements by supervisors or decision-makers about the employee's pregnancy, anticipated leave, or expected family priorities. When such statements are made by the actual decision-maker in close temporal proximity to the promotion decision, courts treat them as direct evidence of discriminatory intent rather than inadmissible stray remarks. Promotion denials are often accompanied by pretextual justifications (the other candidate was "a better fit," the position was "restructured") that look different when examined against the backdrop of pregnancy disclosure timing and the comparative qualifications of the candidates.

Demotion and Pay Reduction

Reassigning a pregnant employee to a lower-paying or lower-status position while pregnant, reducing her pay or benefits because of pregnancy, or stripping her of supervisory or substantive responsibilities without legitimate business justification constitutes pregnancy discrimination. Courts analyze demotion claims through the same disparate treatment framework as termination claims: was the demotion motivated by the employee's pregnancy? Would a similarly situated non-pregnant employee have been demoted? Was the stated reason for the demotion pretextual?

Demotion claims are particularly valuable when the employee was never restored to her original position or pay level after returning from maternity leave. In those cases, back pay accrues based on the wage differential for the entire period of reduced compensation, and the damages can be substantial over time.

Constructive Discharge and Hostile Work Environment

Constructive discharge occurs when an employer deliberately makes working conditions so intolerable that a reasonable employee in the plaintiff's position would feel compelled to resign. In pregnancy discrimination cases, this can be established by showing that the employer systematically stripped the employee of meaningful work, subjected her to constant harassment, refused all accommodation requests, or made clear that her continued employment was unwelcome because of her pregnancy. Courts treat constructive discharge as equivalent to actual termination for damages purposes.

Pregnancy-based harassment that does not rise to constructive discharge may still support a hostile work environment claim if it is severe or pervasive enough to alter the terms and conditions of employment. The totality of the conduct matters: isolated comments, while offensive, typically do not constitute a hostile environment, but a pattern of demeaning treatment, exclusion, pressure to resign, or derogatory commentary can. Supervisor harassment is treated more seriously than coworker harassment, particularly when the employer knew about it and failed to take corrective action.

FMLA Retaliation

An employer that takes adverse action against an employee for taking FMLA maternity leave violates both the FMLA and may also violate the PDA, depending on the facts. FMLA retaliation claims require: protected activity (taking approved FMLA leave); an adverse employment action; and a causal connection between the two. The most compelling FMLA retaliation pattern is termination upon return from leave — timing alone can establish the causal connection when no performance issues were documented before leave commenced. FMLA remedies (back wages, liquidated damages, attorney fees) are separate from and potentially additive to Title VII pregnancy discrimination remedies, and unlike Title VII, FMLA damages are not subject to a per-employer-size cap.
